Why not use some of her art work on the walls, in different size and style frames (natural, black, white & silver) - you can pick up some cheap frames in the op shop and the bargain stores - just buy some spray paint, and have fun - let your artist help....... you can even photograph some of her art work and have it blown up to poster size - the brighter the better. I'd suggest painting the walls white, with maybe a feature wall a timber bed head - one with a book shelf would be great - a double of course - the room is big enough. A rug to anchor the bed and some funky cushions. An Eames DSW white retro chair and a small white desk with some floating white shelves for odds and ends.... I'd probably get a white roller blind for the window, and paint the door, wardrobe doors and skirtings white, and a lovely large retro style light fitting in the middle of the room, or a hanging pendant next to the bed. A small bedside table - try Ikea - they have a great range, and not too expensive, you may even be able to get a great bedhead there - she sounds a very practical girl, so no frills. You want a young, fresh, modern look. Place the artwork randomly, in groups, on the walls - hang paper cut outs on the walls with blue tack, to see the effect, before you put up the art - Your artist could help with that too. What's her favourite colour??? Does she have any hobbies?? We need photos and more info.... What a lovely step dad you are!!! Good luck. I hope I've helped...

We have old Tasmanian Oak floors that are a warm light toffee colour and painted our walls in a slightly cool white (Caspar White Quarter) and to me it jars a bit as it makes the wood look more orangey. I wish I'd done a white with a bit of warmth (though stay away from daggy creamy whites!). Dulux Natural White I think is perfect and I've seen it used a lot and always looks perfect. (Though get Haymes paint, it's much better, the paint shop can mix it up in any brand's colour).

I agree with Jan -- a lot is personal , and your lifestyles . You say neutral colours , so a wheat type colour for the carpet is a good middle of the road choice , but maybe not practical with kids who like crayons and facepainting and stripping down motorbikes haha . So in that case , maybe a burgundy or mid blue or similar 'solid' colour may suit better ( burgundy may tie in more with the exterior tones ) , but is still sort of neutral , but what about furniture and linen and artwork -- if you have royal blue or fluro green drawers and a brown chair and sunshine yellow duvet/dooner cover , and the room is for someone older than 4 , then burgundy carpet mightn't be the go haha . The existing wall colour works with most things , you can add artwork or posters or sports or academic certificates -- maybe back to front , but I'd sort out everything else ( carpet , furniture , etc ) before deciding on a wall colour , unless sticking to the existing or similar colour .

Hi there, If you want to keep it very soft and light then Terrace White a great choice. If stark is your concern its a great opportunity to add some more interest with colour/depth. Colour wise, something to compliment the terracotta but sits well with grey could be Dulux Snow Season Quarter or Subdue Half. Darker you could try Wet clay or match the darkest colour in the marble vein. Please check paint samples first.
